India is ranked third only to Bangladesh and Pakistan on worst air quality. PM 2.5 concentration in India is 5.2 times above the WHO annual air quality guideline. Air pollution was the fourth leading risk factor for early death worldwide, surpassed only by high blood pressure, tobacco use, and poor diet. Pollutants equal to or smaller than 10 and 2.5 microns in diameter (PM10 and PM2.5) can enter the bloodstream causing cardiovascular and respiratory impacts. Yet, we have some of the best places with the World’s cleanest air.
An AQI between 0 and 50 is considered ‘good,‘ 51 and 100’ satisfactory,’ 101 and 200′ moderate,’ 201 and 300′ poor,’ 301 and 400 ‘very poor,’ then 401 and between 500 is considered ‘severe.’ The concentration of an air pollutant is given in micrograms (one-millionth of a gram) per cubic meter air or µg/m3.
